Description

Technical Field

[0001] This utility model relates to the field of sand making machine technology, specifically a grading and screening vibrating feeding device for a vertical sand making machine. Background Technology

[0002] Vertical crushing machines are widely used in the crushing of manufactured building sand, stone and various metallurgical slags. They are also widely used in the medium and fine crushing of high-hardness and extra-hard materials such as various ores, cement, corundum, and glass raw materials. Compared with other types of crushers, vertical crushing machines have a simple and reasonable structure, low operating cost, and utilize the stone-on-stone principle, resulting in less wear, high crushing rate, energy saving, and fine crushing and coarse grinding functions.

[0003] Publication No. CN221452760U discloses a vertical sand making machine grading and screening vibrating feeding device. It utilizes a roller in the crushing assembly to drive the crushing teeth to rotate. As the crushing teeth rotate, they carry large pieces of stone into the inner cavity of the crushing chamber. During this movement, the large pieces of stone collide with the collision bars, and the relative movement between the crushing teeth and the collision bars compresses the large pieces of stone, breaking them into smaller particles. By incorporating a crushing assembly, it solves the problem of the lack of a stone crushing device in grading and screening feeding devices, reduces the destructive force of the stone on the device, and extends the device's service life. Smaller stone particles enter the grading and screening device, which also improves the stone grading and screening effect. However, this patent still has the following problems in practical use:

[0004] When crushing large stones, the vertical crushing machine's grading and vibrating feeding device can easily cause stone blockage at the feed inlet. At the same time, large stones can get stuck on the crushing scale, preventing the crushing teeth from rotating, which is not conducive to crushing large stones. In addition, it cannot evenly feed the material into the screen box, causing the stone to accumulate in one place in the screen box, thus affecting the screening efficiency of the screen box.

[0005] Therefore, a vertical sand making machine grading and screening vibrating feeding device is proposed to solve the problems mentioned above. Utility Model Content

By starting the crushing motor to drive the first rotating disk to rotate, and the rotating connecting rod to drive the second rotating disk to rotate, the reciprocating rotating plate drives the second crushing plate to rotate, which can crush the stone used for sand making.

[0021] 2. By setting up a grading and vibrating screening mechanism, not only can the vibrating motor drive the entire screening box to vibrate, but the screening screen will also vibrate under the action of the first vibrating spring, thus achieving the screening function.

This not only allows the cleaning brush to be rotated to the top of the screening screen during screening, avoiding damage to the cleaning brush caused by the vibration of the screening screen, but also allows unidirectional cleaning of the screening screen by rotating the cleaning brush, thereby improving the cleaning effect of the screening screen.

The locking pin 217 is engaged with the rotating knob 212 through the locking hole 214. The vibration motor 207 drives the entire screen vibration box 204 to vibrate, and at the same time, the first vibration spring 209 causes the screening screen 210 to vibrate, thus realizing the screening function. By rotating the knob 212, the cleaning sliding rod 211 and the cleaning brush 213 slide inside the cleaning chute 205, which can continue to clean the screening screen 210 and avoid clogging of the screening screen 210. The system can discharge stones that have not passed through the screening screen 210 through the cleaning chamber door 206.

This not only allows the cleaning brush 213 to be rotated to the top of the screening screen 210 during screening, preventing the vibration of the screening screen 210 from impacting the cleaning brush 213 and causing damage, but also enables unidirectional cleaning of the screening screen 210 by rotating the cleaning brush 213, thereby improving the cleaning effect of the screening screen 210.

[0032] Working principle: Before using this type of vertical crushing machine grading and screening vibrating feeding device, it is necessary to check the overall condition of the device to ensure that it can operate normally. Figure 1 - Figure 6As shown, firstly, the first translation motor 103 drives the first sprocket transmission assembly 104 and the first translation threaded rod 105 to rotate, which in turn drives the crushing box 107 to move via the first translation threaded sleeve 106, enabling uniform feeding of the screen vibrating box 204 and thus improving the screening efficiency of the screen vibrating box 204. Simultaneously, the second translation motor 109 is started, driving the second sprocket transmission assembly 110 and the second translation threaded rod 111 to rotate, causing the second translation threaded sleeve 112 to move the first crushing plate 113. This allows adjustment of the distance between the first crushing plate 113 and the second crushing plate 119, preventing stone blockage and controlling the fineness of the sand. The crushing motor 114 is started, driving the first rotating disk 115 to rotate, which in turn drives the second rotating disk 117 to rotate via the rotating connecting rod 116, causing the reciprocating rotating plate 118 to drive the second crushing plate 119 to rotate, thus crushing the stone used for sand making. Secondly, the vibrating motor 207 drives the entire screen vibrating box 204. Vibration is generated, and the screening screen 210 vibrates under the action of the first vibration spring 209, thus achieving the screening function. By rotating the knob 212, the cleaning sliding rod 211 and the cleaning brush 213 slide inside the cleaning chute 205, which can continue to clean the screening screen 210 and avoid clogging. At the same time, stones that have not passed through the screening screen 210 can be discharged through the cleaning chamber door 206. By rotating the knob 212, the cleaning sliding rod 211 and the cleaning brush 213 can be rotated. The locking pin 217 and the locking hole 214 can be used to fix the rotating knob 212 and the cleaning brush 213. This not only allows the cleaning brush 213 to be rotated to the top of the screening screen 210 during screening, preventing the vibration of the screening screen 210 from hitting the cleaning brush 213 and causing damage, but also allows the screening screen 210 to be cleaned in one direction by rotating the cleaning brush 213, thereby improving the cleaning effect of the screening screen 210.
